It was standing room only and we had a visitor in VK2 Bob VK7BS who has moved down here and is about to become a member of REAST.
The room was setup in a theatre of the round configuration with a big table in the middle with three different Oculus Rift headsets (DK1, DK2 and CE1), computers, high power video cards, controllers and cameras.
Ian then took the audience through the video games that pioneered 3D and VR with Doom and Quake. We started to see standardised 3D gaming engines that most manufacturers adopted.
Ian Mackintosh started with a presentation on Virtual Reality (VR) Archeology. Starting in 1965 with Ivan Sutherland and Ian took the audience through the development of computer graphics and specifically three dimensional computer graphics. The VR boom took off in 1970-80s with Atari with arcade games which overtook the military applications and development. The game that took Atari to another level was Star Wars with vector graphics and Ian bought along service manual for this game. The 1990 saw NASA put resource toward VR along with Nintendo Virtual Boy and SEGA cockpit arcade game. But unfortunately each manufacturer would custom build and develop the hardware and software. Most of these were commercial failures. Ian then went through the VR Recipe including 3D hardware, multi-thread multi core processors, six degrees of freedom, 3D audio, etc.
Over the last couple of months there has been a noticeable degradation of the VK7RAD 2m Analogue FM repeater, with increased noise and crackling on the audio, and people requiring more power to get in to the repeater.
Additionally the club had been loaning a Bushcomm SWC-100S Antenna from VK7FAZE for 3 years, but it’s power limitations for non-SSB transmissions meant it was also time for a more permanent antenna to be procured and the loan returned.
A TET Emtron ED-52c was purchased as a replacement multi-band HF antenna and a Diamond X50N and these were installed last weekend, where it was discovered that the Heliax feed line to the repeater antenna was damaged, and it too has been replaced.
All up, a good 3 hours was completing the necessary maintenance and has been well worth it, with many users of the repeater mentioning the improved quality of the signal and Dave VK7DM is also reporting that where he used to need 40 Watts to get into the repeater with a clean signal, he now needs only 1 Watt!.
Thanks to VK7s SD, ZMS, ZBX, ZCR, FPCL and BEN for their assistance on the day with the maintenance work!
The observant will have noticed that our last post was in November 2018. This certainly doesn’t mean that the club has been shut down since then, there has been a lot going on and we just haven’t had time to update you on the website!
That is now changing, and we will be getting you up to date with all the happenings over the coming weeks!
